So I'm A Celebrity is back with some famous faces (and some less so) in the jungle to take on their biggest fears.

But how much are they being paid to eat kangaroo testicles and cockroach smoothies?

What each celebrity gets paid is a closely guarded secret but this year Caitlyn Jenner, unsurprisingly is rumoured to be the biggest earner taking home a reported £500,000 fee.

Ant and Dec even referred to it in the opening section of the first episode on Sunday night.

Introducing the show, Dec said: "We've got reality TV royalty Caitlyn Jenner. Most people come into the jungle to lose a few pounds," with Ant adding: "But she's going to be gaining 500,000 of them according to the papers."

Dec then responded, telling Ant, "Don't believe everything you read in the papers, Ant. You know that."

The pair went on to say, "I'm A Celebrity 2019 can only have one winner. Caitlyn Jenner's agent by the sound of it."

So whatever she's being paid, it's fair to assume it's a fair chunk.

Other rumours for the celebrity fees include Ian Wright, who is said to have agreed a £400,000 fee, followed by ex-Girls Aloud singer Nadine Coyle, who will apparently be paid £250,000, according to LadBible.

Good Morning Britain's Kate Garraway and former EastEnders actress Jacqueline Jossa are reportedly getting a sweet £75,000 each. 

Both rugby star James Haskell and Radio 1 DJ Adele Robers are said to be getting £50,000 each, while rumour has it   Capital FM DJ Roman Kemp is on a £40,000 fee and Myles Stephenson, who sings in X Factor winning band Rak-Su is earning £25,000.

It's not known what Irish comedian Andrew Maxwell will be paid.
